Description

Technical Field

[0001] This utility model relates to the field of building construction technology, and in particular to an intelligent visual construction hoist automatic door opening and closing system. Background Technology

[0002] A construction hoist, also known as a construction elevator or building elevator, is a type of mechanical equipment specifically designed for the vertical transportation of materials, tools, and personnel on construction sites. It typically consists of a steel frame structure, a lifting platform, a drive system, and a control system. Driven by an electric or hydraulic system, it can quickly and safely transport heavy objects or personnel to different floors. Automatic door opening and closing is a safety feature of construction hoists, installed at the entrance and exit of each floor. Its function is to automatically open when the hoist car reaches the target floor and automatically close after personnel or materials have entered or exited.

[0003] Because the guide support of the construction hoist is built from the ground, as the number of floors in the building gradually decreases, the gap between the hoist car and the building will gradually increase, making it very easy for people or small tools to fall through this gap. Utility Model Content

[0004] The main purpose of this utility model is to provide an intelligent and visual automatic opening and closing system for the landing doors of construction hoists, which aims to dynamically fill gaps through an intelligent linkage bridging mechanism, eliminate safety hazards during passenger and passenger descent, and improve the level of automation.

[0005] To achieve the above objectives, the present invention proposes an intelligent visual construction hoist automatic door opening and closing system, comprising a door frame fixed to the entrance of a building floor, a door body installed on the inner side of the door frame, and a door opening and closing mechanism, and further comprising: A bridging mechanism, comprising a movable flap and a bridging drive assembly, wherein the movable flap is hinged to the bottom edge of the outer side of the door frame, and the bridging drive assembly is used to drive the movable flap to rotate around the hinge axis, switching between a closed state and an open state. The linkage control module is connected to the landing door opening and closing mechanism, the bridging drive component and the elevator control system. When the car stops at the target floor, it triggers the door to open and drives the movable flap to flip in the direction of the car.

[0006] In one possible implementation, the bridging driver component includes: A drive motor is fixed inside the door frame, and its output shaft is rigidly connected to a crank. The linkage structure includes a first link and a second link. One end of the first link is eccentrically hinged to the crank, and the other end is connected to the second link through a first revolute joint. The end of the second link is connected to the non-hinged end of the movable flap through a second revolute joint.

[0007] In one possible implementation, the end of the movable flap is provided with an overlapping structure, the overlapping structure including an elastic buffer pad embedded in the lower surface of the end of the movable flap.

[0008] In one possible implementation, the door frame is provided with a guide rail to constrain the flipping path of the linkage structure.

[0009] In one possible implementation, the upper surface of the movable flap is provided with an anti-slip rubber layer, and the surface of the anti-slip rubber layer is formed with anti-slip ripples.

[0010] This utility model's technical solution uses a bridging mechanism composed of a movable flap and a bridging drive component to dynamically fill the gap between the landing door and the car. The linkage control module synchronizes the opening and closing of the door and the flipping of the flap. Combined with the anti-slip layer and guide rail, it improves safety and positioning accuracy, eliminates the risk of people falling, and achieves automated and efficient boarding and alighting.

[0014] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0015] To address the problems in the background technology, this utility model proposes an intelligent and visual construction hoist automatic door opening and closing system, including a door frame 1 fixed to the entrance of a building floor, a door body 2 installed on the inner side of the door frame 1, and a door opening and closing mechanism 3, and further including: The bridging mechanism 4 includes a movable flap 41 and a bridging drive assembly 42. The movable flap 41 is hinged to the bottom edge of the outer side of the door frame 1. The bridging drive assembly 42 is used to drive the movable flap 41 to rotate around the hinge axis and switch between the closed state and the open state. The linkage control module is connected to the landing door opening and closing mechanism 3, the bridging drive component 42 and the elevator control system. When the car stops at the target floor, it triggers the door 2 to open and drives the movable flap 41 to flip in the direction of the car.

[0016] Combined with reference Figures 1 to 2 As shown, in this embodiment, the landing door frame 1 is welded from high-strength aluminum alloy or steel structure and firmly fixed to the concrete embedded parts at the building's landing entrance. The inner side of the frame is equipped with vertical slide rails and a top load-bearing crossbeam. The crossbeam has embedded channels specifically for laying cables and sensor components. The door body 2 assembly is installed inside the landing door frame 1, i.e., on the side facing away from the construction hoist car. The landing door opening and closing mechanism 3 includes a motor and a transmission gear set, responsible for driving the landing door body to reciprocate along the slide rail mechanism. The door body 2 is connected to the frame slide rail via a pulley system, and its top is linked to the servo motor of the landing door opening and closing mechanism 3 via a synchronous belt, thereby achieving smooth horizontal bidirectional movement of the landing door.

[0017] A bridging mechanism 4 is installed at the bottom edge of the frame near the elevator car (outer side) via a hinge shaft. This mechanism consists of a movable flap 41 and a bridging drive assembly 42. The movable flap 41 is a lightweight aluminum alloy plate with a non-slip rubber layer 6 on its surface. In its initial state (when the landing door is closed), it is parallel to the landing door frame 1 (i.e., perpendicular to the ground) and tightly adheres to the outer edge of the frame, forming a closed protective surface. When the landing door is fully opened, the bridging drive assembly 42 (such as an electric push rod or rotary cylinder) drives the movable flap 41 to rotate 90° clockwise around the hinge shaft, switching it from a vertical state to a horizontally unfolded state. At this time, one end of the flap remains fixed to the edge of the frame, while the other end extends horizontally to the elevator car entrance, seamlessly connecting with the car floor to form a continuous passage platform, completely eliminating the potential danger of a large gap between the landing and the car.

[0018] The linkage control module is the intelligent core of the system, employing an industrial-grade PLC with a built-in multi-threaded logic control program. It is interconnected with the elevator control system, landing door opening and closing mechanism 3, bridging drive component 42, and visualization module via CAN bus or Ethernet communication. When the elevator car is positioned to the target floor by the leveling sensor, the linkage control module receives the car's position signal. Its logic control flow is as follows: when the landing door is closed, the movable flap 41 is in a vertical state, completely parallel to the outer plane of the landing door frame 1, without occupying external space; when the elevator car is leveled, the linkage control module first drives the door 2 to open synchronously with the car door. After the door 2 displacement sensor confirms that the door is in place, it triggers the bridging drive component 42 to rotate. The bridging drive component 42 drives the movable flap 41 to rotate at a constant angular velocity. When the flap rotates to a horizontal state, its free end contacts the car floor through a spring buffer contact, ensuring a seamless connection without rigid impact.

[0019] In one possible implementation, the bridging driver component 42 includes: A drive motor 421 is fixed inside the door frame 1, and its output shaft is rigidly connected to a crank. The linkage structure 422 includes a first link 4221 and a second link 4222. One end of the first link 4221 is eccentrically hinged to the crank, and the other end is connected to the second link 4222 through a first revolute joint. The end of the second link 4222 is connected to the non-hinged end of the movable flap 41 through a second revolute joint.

[0020] Combined with reference Figures 1 to 2 As shown, in this embodiment, the drive motor 421 (not shown) is a stepper motor or a servo motor, which is rigidly fixed in the mounting base on the side wall of the door frame 1 by a flange. The motor output shaft extends to the outside of the frame and is rigidly connected to the crank by a keyway and a locking nut. When the drive motor 421 starts, the output shaft drives the crank to make a circular motion around the axis. The rotational motion is converted into reciprocating oscillation through the first connecting rod 4221, and then transmitted to the movable flap 41 through the second connecting rod 4222, driving it to rotate around the bottom hinge axis. When the crank rotates half a revolution, the movable flap 41 completes the full stroke from the vertical closed state to the horizontal unfolded state (90° flip).

[0021] In one possible implementation, the end of the movable flap 41 is provided with an overlapping structure, the overlapping structure including an elastic buffer pad 5 embedded in the lower surface of the end of the movable flap 41.

[0022] Combined with reference Figures 1 to 2As shown, in this embodiment, the elastic buffer pad 5 is embedded in the rectangular groove on the lower surface of the end of the movable flap 41 by countersunk bolts. The depth of the groove is 2 / 3 of the thickness of the buffer pad to form a limiting constraint. The bottom surface of the buffer pad is provided with a wavy anti-slip texture, which forms a friction self-locking with the anti-slip steel plate on the surface of the car sill, and can absorb the impact energy generated by the vibration of the car through the elasticity of the material.

[0023] In one possible implementation, the landing door frame 1 is provided with a guide rail to constrain the flipping path of the linkage structure 422. Specifically, the end of the second link 4222 of the linkage structure 422 is welded with a roller assembly, the rim of which is embedded in the groove of the guide rail. The planar motion trajectory of the link is constrained by rolling friction, ensuring that when the movable flap 41 is unfolded, its end overlaps the surface of the car sill, covering the horizontal gap between the door 2 and the car.

[0024] In one possible implementation, the upper surface of the movable flap 41 is provided with an anti-slip rubber layer 6, and the surface of the anti-slip rubber layer 6 is formed with anti-slip ripples 61. Specifically, the edge of the rubber layer extends to the side wall of the flap to form a edging structure, and is bonded and fixed to the aluminum alloy substrate of the flap with epoxy resin. The surface is molded with continuous transverse anti-slip ripples 61 to increase the friction coefficient of the contact surface and prevent people from slipping and falling. Folding guardrails can also be added to both sides of the movable flap 41.
